The MXDF catalog was constructed in two ways, a blind emission search in the MUSE cube (ORIGIN method) and spectra extraction with prior information (ODHIN method). The two types of information were merged into one catalog (Bacon et al. in prep.). Appendix REF  gives a brief summary of the ORIGIN and ODHIN methods, the flow of the visual inspection, assignment of [1]}'s ID (RID), and the criteria of confidence levels (ZCONF) of spectroscopic redshifts (spec-\(z\)  or \(z_{\rm s}\) ). The MUSE sources that are included in the catalog of [2]} keep the same ID (MID) in the MXDF catalog. Most of the continuum-bright sources in [1]} are spectroscopically confirmed in the MXDF catalog. For instance, in the region with more than 100-hour integration (\(r<31\)  arcsec), 87% of HST/Advanced Camera for Surveys Wide Field Channel (ACS/WFC) \(F775W\le 27.5\)  sources have reliable spectroscopic redshifts, ZCONF=2 or 3, and 7% have ZCONF=1 redshifts. Moreover, 25 sources out of 26 \(F775W\le 27.5\)  galaxies, whose photometric redshifts (photo-\(z\)  or \(z_{\rm p}\) ) are within the targeted redshift range below, have ZCONF=2 or 3 (see Figure REF  in Appendix REF ). The spec-\(z\)  for the remaining 1 source was assigned as explained below. We note that we used a preliminary version of the MXDF catalog (DR2 v0.8) in this study.
